Spied: Cadillac ATS-V and a production 2013 Cadillac ATS on the road

Autoweek reader Christina McNeal shot these photos of a 2013 Cadillac ATS out cruising the highways of Michigan. General Motors' BMW 3-series fighter was finished in a metallic dark blue and wore manufacturer plates. According to its badging, it was powered by Cadillac's 3.6-liter six.

Citroën DS Wild Rubis concept

The Citroën DS Wild Rubis concept is the French manufacturer's foray into the premium SUV market, to be shown at the Shanghai auto show next Saturday. At 4,700mm long it's slightly larger than a BMW X3 or Audi Q5, with a particularly generous wheelbase of 2,900mm, presumably to offer the rear passengers a little more space - major consideration in China. It was designed in the DS studio in France, something the company is keen to promote given China's desire for chic European luxury goods.

Chrysler Sebring

Chrysler has shown pictures of the 2007 Sebring, a mid-sized sedan that will enter production in America later this year. New from the ground up, the dynamic exterior borrows cues from the Crossfire in the front three-quarter, while a part-masked C-pillar helps accentuate the Sebring's arched cab, eschewing the 'chopped' look of the larger 300C. The urbane interior features an IP with a broad panel theme, reminding slightly of the Mercedes-Benz CLS/> It will be available from launch with the option of two V6 engines and, unusually, a new four-cylinder motor that produces 172PS from 2.4 liters.
